:or creano, vo ixiol eaiNmN'e Nn roLxeHiNe Madamamachine for grinding the seats and balls used in the valves of oil wells or deep water wells.

The invention also has for its object t0 provide a grindinginachine which in addition to being and balls of valves used in oil 4and water wells is' also adapted to be used for rasping the rings on the standing valves in such wells. v

The invention has for its object to provide an improved grinding machine of this chary acter, 'by means of which balls and seats of the valves for oil wells may be effectively ground and the rings 'of the valves of an oil well thoroughly rasped. v

The invention consists in a grinding inachine of this character and in details of construction 'thereof as hereinafter set forth and claimed.

In the drawing, Figure 1 is a side view in elevation of a grinding -machine lconstructed in accordance with this invention. Fig. 2 is an enlarged detail view in Apers iective of the clamping member of the ma chine. Fig. 3 is a detail view in perspective of a rasp, used with said machine. Fig. 4 is a side view in elevation of the machine with certain parts thereof removed. Fig. 5 is a plan view of the machine'showiiig a rasp and standing valve 4mounted thereon.

A grinding@- machine constructed in accordance with*` this invention comprises a frame formed with a suitable base portion and as here shown consisting of two longitudinal strips 1 set up onl edge and spaced ap..rt from each other and connected tol suitable bolts or rivets 1, the base portion 1fis supported by transverse i'latv gether by strips 2 each of which have a hole 8 at its ends for the reception of bolts to secure said plates 2 to a floor, said plates or strips 2 being secured to the base 1 by means ot` a vertical bolt 4 connected with said strip midway between its ends and clamped to f Specification of Letters 'a'tent. f Application nieu VJuiy s, 1910. serial No. 576,989.

' i the stri used for grinding the seats y s 1 by means of a washer, andv nut on t e bolt 1.1 Parallel with and spaced at. some distance abovezthe basel are two transverse metallic strips 6, similar to the strip 1 and secured together by bolts 6', and

spaced apart from each other. The pairs of strips 1 and 6 are connected together by uprights 7, of any suitable shape. '.Each of the pairs of strips 1 are formed midway between their ends with enlar ed curved Patented Nov.A 2.9. 1910? l ortions 8, the portions 8 in t e strips'l'. y,

orming a seat for a horizontal beveled gear vertical'shaft 10, which has its bearing adja'- wheel 9 mounted on the lower end ,ofthe-f cent to its upper end in the enlarged cir-V cular portion 8 of the strips 6 and projects beyond the same, and ftermin'ates'in an enlarged circular head 11 in which is seated the stem of a circular head `12 [clamped formed of canvas belting, canvas Vfelt 4or emery grinding disk 14 as shown in F-ig. 4.) Meshing with the horizontal isa vertical beveled gear whee l15 mounted its bearings in an upright v17r of the frame having at its outer end a crankshaft 18.v

The circular head 12 is preferably formed of l metal,l and secured thereto is a disk y14 cork. Upon the 'disk 14 isniounted an 19 indicates a valve seat of an oil well andv Y 2O a lball used with said valve seat, said ball being positioned on the disk 14 ywhich is covered with metal powder. The seat'19 rrests in a socket in the transverse plate 21'which is pivotally connected at l`itsends with the upper ends of a pair of reciprocating shaker bars 22'pivoted at their lower ends to the strips 1 forming the base.` The seat is held in place and presses against the ball 20 to hold it in position on the disk 14 by means of a plate 23, hinged at one end to a short post 2i and projecting up from the strip 21 and retained in place by anut 25 on the en d of an attenuated portion of the post- 24. The l may be clamped down against the seat 19.

In order to reciprocate the shaker bars 22,v one-of said lbars is connected by a link 29 at one end to a projection 30 on said bar'and at its other eid to the ends 31 encircling an eccentric 32 pivoted AShaker of a strap wing nut 28 by means of which the plate 23 I 'atm balie: of the shaker" bars' f tachablej lbltv 2 1( .and swung out` of the `way .of the'other bar.
